Application mea september 1o, 192,0. serial no. cassa To all 'whom 'itmay concern:

Be it known that jI, JOSEPH DECLAYE, a

subject of the Kingof Belgium, andresid'ent,

of Liege 32 Rue Adolphe Borgnet, Belgium, have invented certain new` anduseful Improvements in or Relating to Cartridge Stop Levers for TubularMagazines of Small Arms; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, -referencebeing had to the accompanying drawings, and to lettersor figures of reference marked. therein, which formapart of thisspecification This invention relates'to a cartridge stop lever fortubular magazine of 'fire arms, which is actuated' by thel motions `ofthe breech bolt so as to cause the checking vof the cartridges and theirreleasing. i.

According to the invention the bolt is provided with a groove which mayengage the end of a finger of the stop lever. The motions of the vboltcause therotation of the stop lever by the engagementand disengagementof the end of said finger in the groove of the breech bolt.

In a particular form of the invention the stop lever is pivoted underthe bolt and has at each end a nose for checking the cartridges, andworks in such a way that when the front nose is releasing a cartridge,the rear nose, although it allows the passing of a second cartridgepushing the first, checks the third cartridge, thus relieving the lirstand second cartridges from the action of the spring.

The accompanying drawings illustrate an application of the invention.

In these drawings:

Fig. 1 shows the positions of the parts when a cartridge is engaged inthe breech ready for firing;

Fig. 2 shows the positions of the parts when the breech bolt which isrecoiling has brought about a rotation of the cartridge stop lever; 1

Fig. 3 shows a position of the parts similar to the position shown inFig. 2 but when the stop lever is releasing one of the last cartridgesof the magazine; and

Fig. 4 shows adetail in front view and in section.

under the action of a spring Tacting onlan arm 8 of the 'said-lever 1.This leverv ispro.- vided with'a finger 5 always kept against the breechbolt by the action of the said spring 7 and becomes engaged in agroove 6ofthe bolt, when said :bolt has-,sufciently recoiled.

When the end Vof the finger 5 engages the groove 6.of the bolt, thelever 1 .is dis; placed and the nose 9' provided at `rits front endreleases the cartridge 10 which was -held nearer in the positionillustrated in Fig. 1. The. j

spiral spring 15, shown in Fig. 3 acting on the cartridges in themagazine, then thrusts the cartridge 10 forward, together with the wholecolumn of cartridges. VWhen tliefcarf tridge 10 is in a position suchthat ity may 4be pushed forward intofthe breech by thefront part of the.breech bolt, this cartridge-10jA is isolated from the pushing action.of` the spring 15.V This isolation is` obtainedby. the nose-14 providedat the rear end of thelever 1 engaging the rim o f the cartridge12.

In order that thetwo lastv cartridges may be properly moved outfof lthemagazine, the

eXtremityofV-the springl constituted off-a flexible rod 16, is providedwith two projections 17 and 18 distanced from each other by the lengthof a cartridge. rIhe first pro* jection 17 is distanced from the end 20of the said flexible rod 16 also by a cartridge length. Thus, when thelast but one cartridge 12 is within the reach of the breech bolt, thatis in the position of the cartridge 10 of'Fig. 2, the nose 14 isolatesthe said cartridge from the action of the spring 15 by checking theprojection 17.

When the last cartridge (13) is in the position of the cartridge 10 ofFig. 2, the nose 14 checks the projection 18. When finally the breechbolt comes forward again, thus causing a further displacement of the.stop lever 1, and the pushing of the cartridge 13 in the breech, thenose 9 of the lever 1 checks-the projection 17.

The inserting of cartridges into the breech is facilitated by a slope 19arranged at the `in Fig. 4. These pieces are arranged at suitableplaces, between two turns of the flexible rod 16. i

While the invention has been illustrated in what is considered its bestapplication it may have other embodiments without departing from itsspirit and is not therefore limited to the structures shown inthedrawings.

VVhatfI claim is:

l. A cartridge stop mechanism,compris ing the combination with a tubularmagazine for the cart-ridges and a breech bolt having av groove therein,of a stop lever adapted to act upon the cartridges in said magazine,said lever being provided with a finger arranged to engage in the groovein said bolt, said breech bolt being arranged to actuate said stop leverto stop and release the cartridges, the movements of the-stop leverbeing caused by the movement of vsaid nger into and 'out of said grooveand said groove being located in the front portion of said breech boltwhereby a cartridge is released only when said bolt is in its rearposition.

2. A cartridge stop lever for` tubular magazine actuated by themovements of the breech bolt so as to cause the checking of thecartridges and their releasing provided with a finger the top of whichmay engage in a groove of the bolt, the rotations of the stop leverbeing caused by the extremity of said finger oing into the groove of thebreech bolt an out of it, this .stop lever having its two ends providedeach with a nose for checking the cartridges and operating in such a waythat when the front nose is releasing a cartridge, the rea-r nose,although. it allows the passing of a second cartridge pushing the iirst7checks the third cartridge thus causing the second cartridge andconsequently the first to be isolated from the action of the spring ofthe magazine.

3. A cartridge stop lever for tubular magazine actuated by the movementsof the breech bolt, the two ends of said lever being provided each witha nose for checking the cartridge and the spring of the magazine actingon the last cartridge by means of a flexible rod provided with twoprojections distanced from each other of a cartridge length the iirstprojection being distanced from the end of the saidlexible rod also of acartridge length, this device operating in such a way that the last twocartridges may regularly go out of the magazine.

il. In a cartridge stop magazine, the combination'with a tubularmagazine for the cartridges7 of a movable stop lever, the two ends ofwhich are each provided with a nose 'tor engaging the flange of acartridge and a breech bolt controlling said stop lever to release theflange of the cartridge when the breech bolt is in its rear position.

In testimony whereof I aiX my signature in presence of two witnesses.
